Spring Boot基础(六)SpringBoot监控

作者:互联网

添加依赖,开启监控功能

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

 

 在properties文件中开启完整健康信息和埋点(由于安全等因素,默认只显示不完整的health信息)

#开启完整健康信息
management.endpoint.health.show-details=always

#将所有endpoint暴露
management.endpoints.web.exposure.include=*

 

启动SpringBoot项目,启动时注意查看启动日志,会发现有这行:

2022-01-22 16:36:12.697  INFO 11064 --- [           main] o.s.b.a.e.web.EndpointLinksResolver      : Exposing 13 endpoint(s) beneath base path '/actuator'

因此访问的路径为IP:port/actuator,访问后得到一串json,可以在json.cn中解析出来查看:

{"_links":{"self":{"href":"http://localhost:8080/actuator","templated":false},"beans":{"href":"http://localhost:8080/actuator/beans","templated":false},"caches-cache":{"href":"http://localhost:8080/actuator/caches/{cache}","templated":true},"caches":{"href":"http://localhost:8080/actuator/caches","templated":false},"health":{"href":"http://localhost:8080/actuator/health","templated":false},"health-path":{"href":"http://localhost:8080/actuator/health/{*path}","templated":true},"info":{"href":"http://localhost:8080/actuator/info","templated":false},"conditions":{"href":"http://localhost:8080/actuator/conditions","templated":false},"configprops":{"href":"http://localhost:8080/actuator/configprops","templated":false},"configprops-prefix":{"href":"http://localhost:8080/actuator/configprops/{prefix}","templated":true},"env":{"href":"http://localhost:8080/actuator/env","templated":false},"env-toMatch":{"href":"http://localhost:8080/actuator/env/{toMatch}","templated":true},"loggers":{"href":"http://localhost:8080/actuator/loggers","templated":false},"loggers-name":{"href":"http://localhost:8080/actuator/loggers/{name}","templated":true},"heapdump":{"href":"http://localhost:8080/actuator/heapdump","templated":false},"threaddump":{"href":"http://localhost:8080/actuator/threaddump","templated":false},"metrics-requiredMetricName":{"href":"http://localhost:8080/actuator/metrics/{requiredMetricName}","templated":true},"metrics":{"href":"http://localhost:8080/actuator/metrics","templated":false},"scheduledtasks":{"href":"http://localhost:8080/actuator/scheduledtasks","templated":false},"mappings":{"href":"http://localhost:8080/actuator/mappings","templated":false}}}

 

 

 

 

 beans可以查看创建的所有Bean

 

 

 

//这是我之前重写的初始化类
"myApplicationContextInitializer":{ "aliases":[], "scope":"singleton", "type":"com.yz.sprintbootmyun.listener.MyApplicationContextInitializer", "resource":"file [E:\\Work\\Workspace\\sprintboot-my-un\\target\\classes\\com\\yz\\sprintbootmyun\\listener\\MyApplicationContextInitializer.class]", "dependencies":[] },

 

mappings可查查看当前所有url路径

 

 

 "handler":"com.yz.sprintbootmyun.UserController#findAll()",
                            "predicate":"{ [/user/findAll]}",
                            "details":{
                                "handlerMethod":{
                                    "className":"com.yz.sprintbootmyun.UserController",
                                    "name":"findAll",
                                    "descriptor":"()Ljava/lang/String;"
                                },

 

 

这些都是json串,看起来尤其不直观,如果想图形化更直观地查看,可以使用IDEA自带的插件,可以查看常用的几个功能

 

 

如果这还不能狗满足监控使用,那么就可以用SpringBoot-Admin了,admin由一个server和一个或若干个client组成

 

在client中,需要在配置文件中指定server的路径,以及actuator开启的功能

spring.boot.admin.client.url=http://localhost:9000

management.endpoint.health.show-details=always
management.endpoints.web.exposure.include=*

在server中,只需在主类上添加@EnableAdminServer注解即可。如果在同一机器上启动server或client,注意端口不要重复
